binary-tagged: Tagged binary serialisation.

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

Structurally tag binary serialisation stream.

Say you have:

Say you have a data type

data Record = Record
  { _recordFields  :: HM.HashMap Text (Integer, ByteString)
  , _recordEnabled :: Bool
  }
  deriving (Eq, Show, Generic)

instance Binary Record
instance Structured Record

then you can serialise and deserialise Record values with a structure tag by simply

structuredEncode record :: LBS.ByteString
structuredDecode lbs    :: IO Record

If structure of Record changes in between, deserialisation will fail early.

The overhead is next to non-observable.
